Data recorder, data player, playing program, and recording program

Abstract

The present invention at leas comprises an input section 10 for inputting a file, specific media information generation section 12 for generating specific media information, copy restricted file identification section 13 for identifying whether the file is a copy restricted one or not, file conversion section 14 for scrambling the inputted file into a format that can be played back on a specific program, and file recording section 16 for writing the scrambled file or inputted file into the logical address area of a recording media and also writing the specific media information into an area other than the logical address area. If the file is a copy non-restricted one, it is recorded as it. If the file is a copy restricted one, a scrambled file is recorded and the specific media information is written into an area other than the logical address area.

1 . A data recorder comprising: 
 an input section for inputting a data of file;    a file identification section for identifying whether the inputted file is a copy restricted one or not;    a conversion section for converting the copy restricted file into a format that can be played back on a specific program; and    a recording section for storing the file on a recording media if the inputted file is not a copy restricted file, or storing the converted file and the information for running the specific program on the recording media if the inputted file is a copy restricted file.    
   
   
       2 . The data recorder of  claim 1 , wherein the recording section for inputted file or converted file is storing into the logical address area of the recording media and the date for running the specific program is written in an area other than the logical address area of the recording media.  
   
   
       3 . The data recorder of  claim 1 , wherein the copy restricted file includes at least one of a file to which the information showing that a legally rightful person is allowed of copying is described or attached and a file which can be restored by a predetermined procedure.  
   
   
       4 . The data recorder of  claim 1 , wherein the conversion section restores the inputted file by the predetermined procedure and converts it into a format that can be played back on a specific program, if the copy restricted file is a file that can be restored by a predetermined procedure.  
   
   
       5 . A data recording program to control a computer to function as a data recorder comprising; 
 an input section for inputting a data of file;    a file identification section for identifying whether the inputted file is a copy restricted one or not;    a conversion section for converting the copy restricted file into a format that can be played back on a specific program; and    a recording section for storing the file on a recording media if the inputted file is not a copy restricted file, or storing the converted file and the information for running the specific program on the recording media if the inputted file is a copy restricted file.    
   
   
       6 . The data recording program of  claim 5 , wherein the recording section for inputted file or converted file is storing into the logical address area of the recording media and the date for running the specific program is written in an area other than the logical address area of the recording media.  
   
   
       7 . The data recording program of  claim 5 , wherein the copy restricted file includes at least one of a file to which the information showing that a legally rightful person is allowed of copying is described or attached and a file which can be restored by a predetermined procedure.  
   
   
       8 . The data recording program of  claim 5 , wherein the conversion section restores the inputted file by the predetermined procedure and converts it into a format that can be played back on a specific program, if the copy restricted file is a file that can be restored by a predetermined procedure.  
   
   
       9 . The data player comprising; 
 a data file playing section for playing back a file recorded on a recording media,    a judgment section for judging whether the file has been converted into a format that can be played back on a specific program,    a restoration section for restoring the file to an original format if the file is judged a converted one,    a playback section for playing back the file recorded on the recording media or the file restored.    
   
   
       10 . The data player of  claim 9 , wherein the judgment section for judging the file converted in case the identification information of the recording media to be referred to on the specific program is recorded into an area other than the logical address area of the recording media.  
   
   
       11 . The data player of  claim 9 , wherein the judgment section for judging the file converted in case the information showing that the file converted is recorded in the logical address area of the recording media.  
   
   
       12 . The data player of  claim 9 , wherein the judgment section for judging the file converted in case the extension of the file recorded on the recording media is an extension recorded beforehand.  
   
   
       13 . The data player of  claim 9 , wherein the judgment section for judging the file converted in case the file recorded on the recording media cannot be restored by other programs.  
   
   
       14 . A data playing program to control a computer to function as a data recorder comprising; 
 a data file playing section for playing back a file recorded on a recording media,    a judgment section for judging whether the file has been converted into a format that can be played back on a specific program,    a restoration section for restoring the file to an original format if the file is judged a converted one,    a playback section for playing back the file recorded on the recording media or the file restored.    
   
   
       15 . The data playing program of  claim 14 , wherein the judgment section for judging the file converted in case the identification information of the recording media to be referred to on the specific program is recorded into an area other than the logical address area of the recording media.  
   
   
       16 . The data playing program of  claim 14 , wherein the judgment section for judging the file converted in case the information showing that the file converted is recorded in the logical address area of the recording media.  
   
   
       17 . The data playing program of  claim 14 , wherein the judgment section for judging the file converted in case the extension of the file recorded on the recording media is an extension recorded beforehand.  
   
   
       18 . The data playing program of  claim 14 , wherein the judgment section for judging the file converted in case the file recorded on the recording media cannot be restored by other programs.
